obviously because you have cruz at these confirmation hearings baselessly asirting we don't know if chalk hagel took money from north korea. you have that sort of reminiscent of joe mccarthy. >> also a story about when he was at harvard alleging -- >> the professors who wanted to overthrow the government at harvard. >> you have that same streak and when i invoke jesse helms, he was an irtabt even to the republican establishment. they didn't really like having jesse helms around for all those years but the resistance from the republican establishment only made him more popular with the republican base. the particular danger of cruz though i think for the republican party is the republican party today is less ideologically and geographically diverse than it was in the days of joe mccarthy. joe mccarthy was around when dwight eisenhower, a moderate republican, was running the country. today the republican party is at a moment when it needs to sort of modernize itself ideological. if a guy like ted cruz is the definition of what conservative purity is, that's a troubling development for the party b
